HAND-VISE.

Specification of Letters Patent.

Patented March 6,1906.

Application filed April 26, 1905. Serial No. 257,479.

To all whom it may concern.-

Be it known that I, SEBASTIAN J. VVELTER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inHand-Vises, of which the following is a specification.

This invention relates to hand-Vises of that generaltype by means ofwhich material being worked upon can be quickly and firmly gripped andconveniently and rigidly held in the hand during such work, though theprinciple involved may be readily adapted to any kind of vise.

Among the salient objects of the invention are to provide a device ofthe character re ferred to capable of instant adjustment to the thing tobe gripped therein and this without the workman removing his hand fromthe handle of the device; to provide a device wherein the same movementwhich tightens the grip of the vise upon the thing being heldsimultaneously locks the adjustable member thereof in the adjustedposition; to provide a device wherein this compound or double movementis controlled through and by means of the handpiece or handle by whichthe device is gripped and manipulated; to provide a device of thecharacter referred to which constitutes in itself a base or block forthe thing being worked upon and which is capable of being used invarious positions, and, in general, to provide a simple and economicalyet a most effective and practicable device of the character referredto.

The invention will be readily understood from the following description,reference being had to the accompanying drawings, in

which Figure 1 is a plan view of one embodiment of the invention. Fig. 2is a longitudinal sectional view of the same. Fig. 3 is a similar viewof a slightly-modified form of the invention. Fig. 4 is across-sectional view of the base member, taken on line 4 4, Fig. 3.

Referring to the drawings, 1 designates the base or body of the device,preferably of steel, having the jaw member 2 and provided with alongitudinally-extending slot 3. Said slot 3 is enlarged at the underside of said base member, as indicated at 4, Figs. 2 and 3, to provide aslideway for a purpose hereinafter referred to. 5 designates a secondjaw member slidably mounted upon said base or body and havingtherethrough a rectangular opening 6, substantially the same width asthe enlarged portion of the slot 3, with which it is adapted to registerwhen the parts are assembled.

7 designates a through member extending through the slot 3 and theopening6 and having secured thereto at its lower edge by means of thescrews 8 a plate 9, arranged to fit flush within the enlarged portion ofthe slot 3, as indicated in Fig. 2, and to slide longitudinally of thebase, together with the sliding jaw member 5. Pivoted to said throughmember 7 is an eccentric or cam member 10, having a threaded barrel-likeportion 11 and a pair of side members 12, which extend downwardly intothe opening 6 on each side of the upper portion of the through member 7and are pivotally connected to the latter by means of a rivet 13. Thelower edges of said side members are curved eccentrically to the pivotat 13 and bear upon the base member 1 at opposite sides of the slot 3.14 designates a screw member passing through and having threadedengagement with the barrel-like portion 11 of said member and isprovided at its outer end with a handpiece or handle 15, by which it isturned, and at its opposite end with a bearing-cap 16, mounted thereuponby a swivel connection and adapted to bear against the jaw member 5 andmove the latter forwardly when turned.

By gripping the handpiece or handle 15 the cam block or eccentric member10, the through member 7, and the sliding jaw 5 can all be movedtogether backwardly or forwardlyupon the base member 1, thus making itpossible to instantly adjust the jaws to any piece of work to be heldtherein. For instance, if a bar of iron A is to be drilled it is placedupon the base member 1 adjacent the jaw 2 and the other jaw member movedup against it. Now by turning the handpiece and actuating-screw 14 adouble or compound action results. The eccentric member 10 is rockeddownwardly on its pivot, which results in drawing upwardly on thethrough member 7 and clamping said through member and eccentric memberto the base member 1 and also in advancing the sliding jaw 5simultaneously into gripping relation with the work A, both the grippingand locking action being perfected by the simple turning of thehand-piece and actuating-screw 14.

In Fig. 3 the lower edges of said side members 12 are provided withnotches 17, adapted to mesh with corresponding notches 18, formed in theupper surface of the base member along the sides of the slot 3. Theedges of said base member and sliding aw are made flush with each otherand are square, whereupon the device can be used edgewise if it isdesired to bore a hole longitudinally through the block A clampedtherein.

While I have herein shown and described what I deem preferredembodiments of the invention, I am aware that modifications can be madetherein without departing from the spirit of the invention, and I donot, therefore, limit the invention to the details shown and described,except in so far as such details are made the subject-matter of specificclaims.

I claim 1. A vise comprising in combination a base or body memberprovided with a jaw and having therein a slot, a cooperating jaw memberslidably mounted upon said base or body member and provided with anopening there in arranged to register with said slot, a looking memberfor locking said base and jaw members together and working through saidslot and opening, and an actuating member operatively connected withsaid locking member and engaging said movable jaw member, whereby tosimultaneously lock said members together and advance said jaw memberinto a tightened gripping position.

2. In a hand-vise, the combination of a base or body member providedwith a jaw and a slot, a cooperating jaw member slid ably mountedthereupon and provided with an opening registering with said slot, athrough member sliding within said slot with said jaw member, a cammember pivoted upon said through member and working in the opening insaid. jaw member and operating to lock said members together, and an actuating member through said cam member and engaging said jaw member,whereby the operating of said actuating member rocks said cam member andadvances said jaw member simultaneously, substantially as described.

3. A hand-vise comprising in combination a base or body member providedwith a aw, a cooperating aw member slidably mounted upon said base orbody member, a through member operatively connected with both of saidmembers and moving with the j aw member, a cam member provided with aneccentrically-disposed cam-surface and mounted upon said through member,and an actuating member having threaded engagement with said cam memberand bearing against said movable jaw member, whereby the turning of saidactuating member operates to simultaneously rock said cam member to locksaid base and jaw members against relative movement and to tighten thegripping hold of the jaw members, substantially as described.

4. A hand-vise comprising in combination a base or body member providedwith a jaw and having therein a slot with ratchet-teeth along its sides,a cooperating jaw member sliding upon said base member and having anopening therethrough, an eccentric cam member provided-wi thratchet-teeth and having operative connection with said base and jawmembers, a combined handpiece and actuating member threaded through saidcam member and bearin against said movable jaw member, where y theturning of said handpiece operates to simultaneouslv advance said jawmember into ti htened gripping osition and to lock said ase and jaw memer against relative sliding movement, substantially as described.
